Hartmut, the engine is certainly not new, but has an overhaul in the last 10 yrs with about 400 hours on it. In annual checked out very strong and the operating temps are normal. Craig

I noticed that a multi Vis oil will drop the pressure being hot. Try 100W oil and see whether there is a difference. You don't need multi vis oil in a hot environment. Also, how old is the engine , how many hours are on it? If the engine is old enough and the main bearings are worn, you are probably better off with thick based stock oil.

Then after I am at cruise, it runs at about 21 lbs or in the middle of the caution range. I asked my a&p and he thinks it probably has to do with the multi-vis oil warming up and the ranges were set long before multi-viscosity was available. He also has another customer with a C-75 coupe that runs in the same range. So what oil pressure does your coupe sit at when cruising? Craig Peterson N87018 #191 btw, solved the brake problem where the pedal needed adjustment and was binding a bit. ________________________________ Earn cashback on your purchases with Live Search - the search that pays you back!
